- Needs two observations at least 14 days apart. Our next read of this page turns this on. Nothing is extrapolated from a single contract.
- Lifetime pace
- $119K/yr estimate
- Lifetime earnings divided by years on Upwork. A floor on historical pace, not a forecast.
- Earnings per job
- $10.5K
- Average contract value to date.
- Recent earnings, per Upwork
- $51.2K
- The "recent" figure Upwork attaches to the directory card, with 1,509 recent hours. Upwork does not publish the window, so it is shown as its number, not ours.
- Realised hourly
- $35/hr
- Total earned over billed hours. Fixed-price work inflates it; compare with the rate card.
